2. Component parts of airfield There are various components of an airport which are structures. The planning and designing of these Airport components are carried out by civil and structural engineers. Prepared by: Bhavya S. Jaiswal

3. Various component of an airfield are as shown below Runway Taxiway Apron Terminal building Control tower Hanger Parking Prepared by: Bhavya S. Jaiswal

4. runway Runway is a paved land strip on which landing and takeoff operations of aircrafts takes place. It is in leveled position without any obstructions on it. Special markings are made on the runway to differ it from the normal roadways. Similarly, after sunset, specially provided lightings are helped the aircrafts for safe landing. The number of runways for an airport is depends upon the traffic. If the traffic is more than 30 movements per hour , then it is necessary to provide another runway. Prepared by: Bhavya S. Jaiswal

5. Types of runway Single runway Two runways Hexagonal runway 45-degree runway 60-degree runway 60-degree parallel runway Prepared by: Bhavya S. Jaiswal

6. taxiway Taxiway is path which connects each end of the runway with terminal area, apron, hanger etc. These are laid with asphalt or concrete like runways. In modern airports, taxiways are laid at an angle of 30 degree to the runway so that aircrafts can use it to change from one runway to other easily. The turning radius at taxiway and runway meets should be more than 1.5 times of width of taxiway. Prepared by: Bhavya S. Jaiswal

8. Apron Apron is a place which is used as parking place for aircrafts. It is also used for loading and unloading of aircrafts. Apron is generally paved and is located in front of terminal building or adjacent to hangers. The size of area to be allotted for apron and design of apron is generally governed by the number of aircrafts expected in the airport. The aircraft characteristics also considered while design. Proper drainage facilities should be provided with suitable slope of pavement. Sufficient clearances must be provided for aircrafts to bypass each other. Prepared by: Bhavya S. Jaiswal

10. Terminal Building Terminal building is a place where airport administration facilities takes place. In this building, pre-journey and post journey checking’s of passengers takes place. Lounges, cafes etc. are provided for the passengers. Passengers can directly enter the plane from terminal buildings through sky bridge, walkways etc. Similarly, the passengers from plane also directly enter into the terminal building.

12. Control Tower The control tower is a place where aircrafts under a particular zone is controlled whether they are in land or in air. The observation is done by the controller through radars and information is carried through radio. The controller from the control tower observes all the aircrafts with in that zone and informs pilots about their airport traffic, landing routes, visibility, wind speeds, runway details, etc. based on which the pilot decides and attempts safe landing. So, control tower is like nerve system of an airport. Prepared by: Bhavya S. Jaiswal

14. Hanger Hanger is a place where repairing and servicing of aircrafts is done. Taxiway connects the hanger with runway so, when a repair needed for an aircraft it can be moved to hanger easily. It is constructed in the form of large shed using steel trusses and frames. Large area should be provided for Hanger for comfortable movement of aircrafts. Prepared by: Bhavya S. Jaiswal

16. Parking This is a place provided for parking the vehicles of airport staff or passengers which is outside the terminal building or sometimes under the ground of terminal building. Prepared by: Bhavya S. Jaiswal
